We’re looking for a strong sales professional with real experience selling virtual card products and Banking-as-a-Service platforms. This person should understand the payments ecosystem well, know how to sell complex financial products, and be comfortable working with fast-moving online businesses.

A big plus is hands-on experience selling to affiliate marketers, media buyers, marketing teams, or clients operating in the performance marketing space.

What we expect:

• Proven experience in B2B sales of virtual cards, payment infrastructure, or BaaS solutions
• Strong understanding of the card issuing / banking / fintech landscape
• Ability to find, approach, and close high-value clients independently
• Confidence in speaking with founders, operators, and decision-makers
• Good understanding of affiliate marketing, traffic teams, media buying, or adjacent industries is a strong advantage
• Fluent English, strong communication, and commercial thinking

What this person will do:

• Build and manage pipeline from outreach to deal closure
• Sell virtual card and fintech infrastructure solutions to relevant clients
• Develop relationships with affiliates, agencies, media buying teams, and other high-volume users
• Work closely with the team on positioning, feedback, and growth opportunities

We need someone commercial, sharp, proactive, and genuinely familiar with this market — not a generic salesperson.

We are looking for a highly experienced Affiliate Marketing professional with a strong reputation, deep industry knowledge, and an extensive network across the affiliate marketing ecosystem.

This is not a traditional Affiliate Manager role.

Your mission will be to build and lead a distributed network of remote Affiliate Ambassadors who can introduce, promote, and sell our product to affiliate marketers, media buyers, affiliate teams, agencies, and other relevant players across the industry.

The Role

We are building a product specifically designed for the affiliate marketing industry and want to scale its distribution through people who already understand this market from the inside.

We are looking for someone who has spent years in affiliate marketing and knows:

• who the serious players are;
• where the strongest affiliate communities are;
• how affiliate teams operate;
• how media buyers make purchasing decisions;
• how relationships and reputation work in this industry;
• and, most importantly, how to recruit people who already have access to these networks.

Rather than building a traditional centralized sales team, you will create a distributed ambassador network consisting of experienced affiliate managers, former affiliate managers, industry connectors, community members, and other well-connected professionals.

Each ambassador will leverage their own relationships and network to generate customers.

Your responsibility is to build this network into a scalable acquisition channel.

What You Will Do

Build the ambassador network

Identify and recruit experienced affiliate managers and other well-connected people across key affiliate marketing markets and communities.

Create the operating model

Define how ambassadors work: territories or communities, lead ownership, attribution, commissions, incentives, reporting, communication, and performance expectations.

Activate existing industry relationships

Use your own network to recruit the first generation of ambassadors and establish credibility for the program.

Train ambassadors

Make sure every ambassador understands the product, its value proposition, ideal customer profile, positioning, objections, and sales process.

Drive performance

Track activity, introductions, qualified leads, conversions, revenue, and ambassador productivity.

Expand internationally

Build coverage across the most relevant affiliate marketing geographies, communities, conferences, agencies, media-buying teams, and traffic verticals.

Create a network effect

Your ultimate goal is not simply to manage affiliates yourself. It is to build a structure where strong people continuously bring in new customers — and where the ambassador network itself becomes a competitive distribution advantage.

Who We Are Looking For

You are likely a strong fit if you:

• Have 5+ years of hands-on experience in affiliate marketing
• Previously worked as a Senior Affiliate Manager, Head of Affiliates, Affiliate Director, Business Development Lead, or similar
• Have an extensive personal network within the affiliate marketing industry
• Personally know affiliate managers, media buyers, team owners, agencies, networks, and other industry decision-makers
• Understand the major affiliate verticals and how their ecosystems differ
• Have attended and built relationships through major affiliate conferences and communities
• Are comfortable recruiting, motivating, and managing people remotely
• Understand performance-based compensation and partner economics
• Can turn personal relationships into a structured and scalable distribution system
• Think like an entrepreneur rather than a corporate employee

What Success Looks Like

During the first stage, you recruit a core group of high-quality ambassadors from your existing network.

You then develop a repeatable model for recruiting, onboarding, activating, and managing them.

As the program scales, we expect to have dozens — and potentially hundreds — of active ambassadors globally, each with access to their own affiliate marketing networks.

The result should be a decentralized sales engine capable of generating a predictable flow of qualified customers.

Why This Role Is Different

We are not looking for someone to manage an existing affiliate program.

We are looking for someone who can build the distribution network itself.

If you have spent years in affiliate marketing, know the right people across the industry, and believe you can turn that network into a global sales force, we want to talk to you.

Your network is the starting point. Your ability to turn it into a scalable organization is the job.

We are looking for a highly connected financial services / international finance professional to build a global network of independent ambassadors and referral partners.

Our clients are businesses and entrepreneurs who need solutions around international payments, crypto-to-fiat / fiat-to-crypto flows, cross-border finance, and international financial structuring.

Your Mission

Build and scale a distributed network of professionals who already advise and influence these clients:

• CFOs and fractional CFOs
• Accountants and accounting firms
• Tax and international structuring advisors
• Corporate service providers
• Crypto / fiat brokers and OTC professionals
• Wealth and financial consultants
• Other trusted intermediaries working with international businesses

Instead of building a traditional sales team, you will turn these professionals into ambassadors who introduce relevant clients from their existing networks.

What You’ll Do

• Recruit the first ambassadors through your own professional network
• Build a repeatable partner recruitment and onboarding model
• Develop commission and revenue-sharing structures
• Train partners on our products and ideal client profiles
• Manage and activate the ambassador network
• Expand the network internationally
• Track leads, conversions, revenue, and partner performance

Who We’re Looking For

You have 5+ years of experience in international finance, payments, accounting, tax advisory, corporate services, crypto/fiat infrastructure, or related industries.

Most importantly, you already have a strong network of CFOs, accountants, financial advisors, brokers, and international business professionals — and know how to turn relationships into a scalable distribution channel.

We're looking for a Lead QA Engineer to own quality across a mobile feed product spanning iOS, Android, and a Go backend. You'll sit in the release path for every feature, bug fix, and A/B variant, making sure nothing ships without being rigorously tested first. This is a hands-on role: you'll be running test suites, managing CI/CD and release tooling, and reading code yourself to understand what actually changed, not just working from a spec. The environment moves fast, so you'll also need to be comfortable smoke-testing incident fixes quickly to unblock releases without cutting corners on safety. You'll work across the full stack, verifying tracking events and A/B test variants on the mobile side while also testing backend behavior in Go. This is a role for someone who wants deep, end-to-end ownership of quality inside a startup that ships constantly.

Details:
Schedule: Full time
Location: Sofia, Bulgaria (Onsite, 5 days a week)
Start: ASAP
Duration: Long-term
English: Fluent

About the project:
The company is building a mobile app with a TikTok-style feed of short, AI-generated browser games created by users. It's an early-stage startup moving at a rapid release cadence, shipping features, bug fixes, and A/B test variants continuously rather than on long cycles. Quality currently rests on how thoroughly each release is tested before it goes out, which is why this role is being built out as a dedicated, owned function rather than something spread thin across the team. The product spans a full stack: mobile clients on iOS and Android, and a Go backend behind them, so testing has to cover both the client experience and the systems underneath it. Because the product runs on experimentation, verifying tracking events and A/B variants correctly is a core part of keeping releases trustworthy. The team is small and fast-moving, so this role carries direct ownership of the release path rather than slotting into an established QA process.

You have:
- Professional QA experience covering both mobile apps (iOS and Android) and backend systems
- Hands-on experience running test suites and working with CI/CD, bug tracking, and analytics tooling — not manual testing alone
- The ability to read and understand code to verify changes, even without writing features yourself
- Ideally, experience QA-ing feature-flagged or A/B-tested mobile products
- Ideally, familiarity with Go or broader backend testing experience
- Ideally, experience with mobile release tooling such as TestFlight or Play Console internal tracks
- Ideally, a background in startups, hyper-casual gaming, or other fast-release-cadence environments
- Willingness to work full-time, strictly on-site in Sofia, Bulgaria

What to do:
- Own quality end-to-end across iOS, Android, and the Go backend
- Run test suites and manage CI/CD and release tooling ahead of every release
- Read and review code changes to understand what shipped and verify it behaves as expected
- Smoke-test incident fixes rapidly to unblock releases while balancing speed with safety
- Verify tracking events and A/B test variants are behaving correctly on mobile
- Build out and improve QA process and tooling as the release cadence and product surface grow

Who we are:

Adaptiq is a technology hub specializing in building, scaling, and supporting R&D teams for high-end, fast-growing product companies in a wide range of industries.

About the Product:

Our client is a major online gaming operator building a next-generation transactional platform for user account management. This is a greenfield project designed to operate in a highly regulated, high-volume environment and support millions of concurrent users. The platform will process financial transactions in real time and must ensure high availability, sub-second performance, data integrity, security, and full auditability. One of the key engineering challenges is maintaining reliability and performance during extreme traffic spikes and peak events. 

The team is looking for strong technical expertise to help design and build a scalable, high-performance, and reliable backend platform that can meet strict security, regulatory, and compliance requirements.

About the Role:

As a Senior Java Engineer, you will design and build the core backend services of the PAM platform from the ground up. You will own features end-to-end, from technical design and implementation to automated testing, production monitoring, and release. You will work closely with Principal Engineers on architecture and technical decisions, contribute to RFCs, and deliver production-ready code. You will have a high level of autonomy and real influence over the platform’s design, while taking strong ownership of reliability, performance, and correctness in a critical financial system.

Key Responsibilities:

• Design and build backend services in Java 17+ (Spring Boot or similar) for wallet transactions, ledger entries, payment orchestration, bonus mechanics, and account state management.
• Develop REST APIs and event-driven integrations using Kafka or similar technologies for player-facing frontends, operations tooling, and external partners.
• Ensure correctness and reliability through idempotent operations, clear transaction boundaries, explicit failure handling, and strong unit, integration, and contract testing.
• Embed regulatory requirements into the platform, including KYC/AML checks, responsible gaming controls, and audit trails.
• Ensure production readiness with metrics, structured logging, distributed tracing, alerting, and participation in on-call rotations.
• Contribute to technical design and RFCs, participate in code reviews, and mentor other engineers.
• Use AI-assisted development tools as part of the daily workflow, following platform standards for context and prompts.
• Support live migration from the existing third-party platform, including parity testing, data validation, and cutover coordination.

Required Competence and Skills:

• 5+ years of backend engineering experience with strong hands-on expertise in Java 17+ and a modern framework such as Spring Boot.
• Proven experience building and operating high-integrity transactional systems such as payments, wallets, billing, banking, e-commerce, or gaming.
• Strong relational database expertise (PostgreSQL or equivalent), including schema design, ACID transactions, locking, and performance tuning.
• Experience with event-driven architecture and messaging (Kafka, RabbitMQ, or similar), including idempotency and retry mechanisms.
• Strong testing practices, including automated unit, integration, and contract tests as part of the standard development process.
• Hands-on production experience with containers, CI/CD pipelines, monitoring/telemetry, and production incident troubleshooting.
• Solid understanding of multi-threading, system architecture, and fault-tolerant design patterns.
• Good written and spoken English, with experience working effectively in distributed, multi-time-zone teams.

Nice to Have:

• Experience in iGaming, sports betting, fintech, or another regulated, high-transaction-volume domain.
• Exposure to Kubernetes and AWS, including VPC, IAM, EKS, and auto-scaling.
• Experience with compliance-driven development, including KYC/AML, responsible gaming, and audit requirements.
• Experience with AI coding assistants and agentic development workflows.
• Polish and/or Spanish language skills.

Why Us:

We provide 20 days of vacation leave per calendar year (plus official national holidays of a country you are based in).

We provide full accounting and legal support in all countries we operate.

We utilize a fully remote work model with a powerful workstation and co-working space in case you need it.

• MQTT
• SPI / I2C
• Git

• IoT-проєкти

   

Умови

• Part-time, проєктна діяльність

NuxGame is a B2B iGaming technology provider. We deliver turnkey casino and sportsbook platforms, game aggregation, and sweepstakes products to operators worldwide, across four product lines: Turnkey Traditional, Sweepstakes Turnkey, Game Aggregation, and Sweepstakes Game Aggregation. Our customers are operators. Their back office teams work in our platform every day, and their players use it every time they deposit, verify their identity, or withdraw.
We are looking for a Product Manager to join our team.

What we expect from the candidate:

• You own the roadmap for your domains and you defend it. Prioritisation is your call to make and to explain, not something you escalate by default.
• You write specifications that an engineer can build from without a business analyst in between: scope and non scope, flows, edge cases, dependencies, acceptance criteria.
• You work with data yourself. You define the metric, pull the number, and check it before you act on it.
• You go deep on the technical side. You read API documentation, review integration contracts, and hold your own in a discussion with engineers.
• You design for many operators at once. Every decision is a decision about configuration, defaults, and backward compatibility, not about a single customer.
• You close the loop after release. A feature that shipped and moved nothing is not a delivered feature.

Requirements

Must have

• 5+ years in product management, with at least 3 years owning payments, fraud and risk, or financial products in iGaming, fintech, or payments.
• Hands on experience with PSP and payment aggregator integrations: REST APIs, request and response construction, webhooks and callbacks, idempotency, status and error mapping, reconciliation.
• Practical understanding of the trade offs between hosted payment pages, iframe, and fully platform hosted cashier flows, including where PCI scope, conversion, and support load land in each.
• Experience with several payment method families: cards, e-wallets, bank transfer and local rails, vouchers, and crypto (networks, confirmations, on ramp providers).
• Experience integrating KYC and AML providers, and owning or building a rule based fraud or risk engine.
• Experience with rule based configuration and player segmentation: defining segments, resolving conflicts between overlapping rules, and giving business users a safe way to change them without a release.
• Working knowledge of the regulatory requirements affecting deposits, withdrawals, KYC, and responsible gambling in at least two or three jurisdictions.
• Data fluency: deposit success rate, approval rate by provider and method, withdrawal processing time, chargeback rate, verification funnel conversion. You can pull these yourself.
• B2B product experience. Our users are operators and their back office staff, not only end players.

• Structured written communication in English. Russian or Ukrainian for internal team communication.

   

Nice to have

• Experience in a multi tenant white label platform serving dozens of operators at once.
• Sweepstakes or social casino experience, where purchase and redemption flows differ from classic deposit and withdrawal.
• Experience with payment orchestration platforms, smart routing, and cascading.
• Experience with Metabase or a comparable BI stack, and enough SQL to validate a number.
• Practical use of AI tooling in the product workflow for discovery, documentation, and analysis.

Your position will include:

Payments and PSP

• Own the payment roadmap across all four product lines and decide what gets built, what gets configured, and what gets refused.
• Own the internal payment gateway as a product: integration contract, provider onboarding, error handling and retries, logs, and the tooling support uses to investigate a stuck transaction.
• Own the technical and product side of PSP relationships and work with our PSP Manager, who owns commercial terms and provider selection.
• Drive deposit and withdrawal conversion: cashier UX, method visibility and ordering, error minimisation, hosted versus platform side flows, retry and cascading logic.
• Own crypto and Web3 coverage: networks, confirmations, on ramp providers, wallet based authorisation and deposits.

• Shorten the time it takes to launch a new provider by standardising the integration, so a new PSP becomes configuration rather than custom development.

   

Fraud, KYC and compliance

• Own the fraud and risk engine: rules and thresholds, risk scoring, verification flows, duplicate account and bonus abuse detection, manual review load.
• Own third party KYC and AML integrations end to end, from provider evaluation and platform requirements through rollout to operators.
• Turn licensing and jurisdictional requirements into configurable platform capability instead of per operator custom work.

• Hold the balance between fraud prevention and conversion, and defend where you put the threshold.

   

Auth and identity

• Own registration and login as a conversion product, including social and Web3 registration.
• Own the relationship between authentication and verification: what a player can do before KYC, what unlocks after it, and how that differs by jurisdiction and by operator.

• Own back office authentication, permissions, and audit logs as an operator facing product.

   

Segmentation

• Own segmentation as a shared service: how segments are defined, evaluated, and consumed across payments, limits, verification, and reporting.
• Make it usable by operators without engineering involvement: rule builder, preview and validation before a segment goes live, predictable behaviour when several segments match one player.

• Own the cost side of it: evaluation performance on large player bases and what happens when a segment changes mid-session.

   

Reporting, limits and responsible gambling

• Own operator facing financial reporting, dashboards, and export tooling.
• Own the limit framework (deposit, loss, wager, session) and geo blocking as jurisdiction aware, operator configurable capability.
• Own the responsible gambling toolset and make sure it satisfies the licences our operators hold.
